Fell and Loeb model radiation from an assumed zero-ADM-mass warp-bubble geometry in an atmosphere. Their relativistic aircraft-scale examples predict strong emission. The geometry-generating source and backreaction are omitted; heating, continuum validity and propagation introduce further limits. These conditional predictions constrain an interpretation, without detecting or demonstrating a drive.
Knuth connects ordered-event projections and measurement-sequence inference to an at-rest 1+1-dimensional Dirac checkerboard model. Coordinated observers, local flatness and chosen amplitudes condition the construction. A mass relationship is hypothesized and higher-dimensional extension proposed. This theoretical lineage supplies context rather than independent UAP observations.
